This invention relates to a weather strip for windows and the like and has for its principal object the provision of a weather strip which can be quickly and economically; in-

s stalled; which will insure an absolutely weather tight joint between the window sash and the frame; and which will exert a constant pressure against the sash to prevent loosenessand rattling. to Another object of the invention is to so construct the strip that it will not interfere with the removal of the sash when desired.

A further object of the invention is to so construct the Strip that it will automatically at accommodate itself to shrinkage and wear between the sash and the frame so as to always insure a tight joint. Uther objects and advantages reside in the idetai'l construction of the invention, wh ch is todesigned for simplicity, economy, and etficiency. These will become more'apparent "from the following description,

in the following detailed description of the invention reference is had to the accompany- 255 ing drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description. 4

ln the-drawing: N Fig. i is a fragmentary perspective view through a typical sliding sash check rail window. 1

2 is a detail perspective view illustrating t e type or weather strip which is employed at the side of the frame, in the fully extended osition. p

Fig. 3 i ustrates the same strip in the compressed position. I

Fig. 4. is a detail cross section through the side of the frame taken on the line t-tFig. l. Fig. 5 is a detail section illustrating the type of strip employed at the'top and bottom of the frame. I In the drawing, the window sash is des1gnated at 10, the side frame member is indicated at l l, the head frame member at 12, and the sill at 13.

Two types of strip are employed for the complete-installation in a sliding sash frame.

i e first type, such as illustrated in Figs. 2, 8,

The first type comprises a channel membottom sash l0.

and t, is employed at the side or sliding ortions of the frame. The second type iilus trated in Fig. 5, is employed at the top and bottom of the frame.

55 her it open along one edge. The open edge is provided with two inwardly turned lips 15. A tongue member 16 projects between the lips 15 and is prevented troni being withdrawn by side flanges 17. 'The tongue memher 16 is formed of asingle strip of sheet metal bent with a shape cross section and provided with outwardly turned edges forming the flanges 17. A plurality of bent, leafsprings 18 are distributed throughout the length oil the channel member ll. lhese springs act to constantly urge the tongue 16 outwardly toward the position of Fig. 2.

lhe second style ofstrip comprises a length of sheet metal 19 hent along its medial line to form a tongue which spreads to form two parallel edges 20 which snugly engage each side of a wooden strip 21. Y

in installing'the weather strip a groove is rahheted in the side. frame member if. in the track of each sash 10. Another groove is rabbeted in the head frame member 12 over the. top of the upper sash and still another groove is rabhetedin the ,sill 13' belowthe A relatively narrow groove is now formed in the sides of both the sash and in the top of the upper sash and the bottom of the lower sash. Sections of the strip of Fig. 5 are now set in the grooves in the head member 12 and the sill 13 550 that they will extend entirely across the opening.'- The channel members it are now out to the height of the window and are set in the grooves inthe'sid'e frame memher 11. 'lhe outer extremitiesof the tongues so 19 at the top and bottom draw window will pass through the open sides of the channel members 14 and rest against the top and bottom extremities of the tongues '16, forming a light joint at the corners.

The tongues 16 are now depressed to the position oi Fig. 3 and the sashis swung into position. When the tongues 16 are released they will he forced outwardly by the springs 18 into the grooves 22 in the sash. The me till ' grooves 22 are formed of less depth than the depth of the tongues 16 so that sufficient play will be allowed the springs 18 to constantly maintain. the tongues 16 firmly against the I} bottoms of the grooves 22.

This spring pressure holds the sash snugly and prevents rattling. It also accommodates any shrinkage in the sash or wear in the grooves. Should it be desired to remove the sash this can be easily done by simply depressing the tongues 16 to the posltion of While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the a1ppended claims, without departlng from t e spirit of the invention.

Having thus described the invention, what is claimed and desired secured by Letters Patent is 1. A weather strip comprising: a channel member having a longitudinal opening along one of its edges; inwardly projecting lips alon the sides of said opening; a tongue mem er adapted'to project outwardly from lips; proi said channel member between said jections formed on said tongue member to prevent withdrawal of the latter; and spring means within said channel member arranged to constantly urge said tongue member outwardly.

2-. A weather strip comprising: a channel member; inwardly turned edges on said chan nel member definin a longitudinal slot therein; a tongue mem er, sald tongue member comprising a metal strip having a U-shaped cross section adapted to project through said slot; flanges formed on said to limit the projection thereof through said slot; and means for urging said tongue member outwardly.

3. A weather stri adapted to be positioned between a window ame and a window sash comprising: a. channel member for placement in a groove in said frame; a longitudinal tongue member projecting from said channel member and arranged for placement in a groove in said sash; andmeans for continuously causing said tongue member to project from said channel member.
